PROCESS OF CARBURETING AIR OR GAS SPECIFICATION forming part of Letters Patent No. 425,877, dated April 15, 1890.

Application filed October 6, 1887- Serial No. 251,636. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL HANFORD, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented new and useful Improvements in Processes of Oarbureting Air or Gas,of which the following is a specification.

This invention relates to a process of differentially carbureting a gaseous fluidsuch as air-so that one portion of said fluid is suitable for heating purposes and another portion of said fluid is suitable for illuminating purposes; and it consists in passing a fluid into a suitable charging or impregnating vapor and causing part of said fluid to make a short circuit through said vapor, and causing another portion of said fluid to make a long circuit through said vapor, all of which and the results secured thereby will more fully appear in the following description and claim.

In the accompanying drawings, Figure 1 illustrates a front View of a carburetor, taken in section in the line y y of Fig. 2, such as is employed in carrying out my process. Fig. 2 illustrates a sectional view taken on the line 00 a: of Fig. 1.

This apparatus is illustrated to show an apparatus for working the process or method,

and in the drawings similar letters indicate corresponding parts.

In the drawings, the letter A indicates a case or box of suitable materiahsuch as metal. Said case has the storage-chambers B C.

- WVith the storage-chamber B communicate the tube G and. the overflow/pipe H. IVith the storage-chamber O communicate the inlet I and the outlets J K and the access-tube L.

D E are evaporating or vapor chambers. lVith the evaporating-chamber D communicate the overflow-pipe M and the access-tube N. WVit-h the evaporating-chamberEcommunicate the filling-tube Q, the outlet 0, and the access-tube P. The drawings show two evaporating-chambers D E; but if the evaporating-space is to be diminished but one evaporating-chamber need be employed, while if the evaporating-space is to be enlarged more than two evaporating-chambers may be employed. The outlets K O are shown'as having'valves S, and the accesstubes L N P and the filling-tube Q are shown as having the openings or mouths closed by caps R. The

chambers O D E have partitions F, which open at alternate portions, as seen in Fig. 2, so that fluid passing through said chambers is compelled to take a winding course.

The operation of the device is as follows': The storage-chamber B is supplied with a light or volatile grade of gasoline, and the storage-chamber O is provided with a heavier or less volatile grade of gasoline. The evaporating-chambers D E are supplied with gasoline from the storage-chamber B. By drawing or pumping gasoline through the tube G into the filling-pipe Q, such gasoline will enter the chamber E, and thence the surplus will pass through the overflow M into the chamber D,whence the surplus passes through the overflow H back into the storage-chamber B. The overflow H is made to rest at a somewhat lower level in the chamber D than the tube J, so that no liquid will flow from the chamber D into the chamber 0. The chamber C is supplied or charged by means of the access-tube L. Fluidsuoh as air or gasis then injected or made to pass through the inlet I into the chamber 0. The gasoline in said chamber 0, being of a heavy or slightly volatile kind, will but slightly impregnate such air entering through the inlet 1, and by drawing off such air through the outlet K such air will have made a comparatively short passage or circuit through impregnating-vapors. The result is that such air is suitable for heating purposes, but not suitable for illuminating purposes, since such air when ignited will generate a flame of a high degree of heat, but giving off a very feeble light. Such air which is not drawn off through the outlet K passes through the tube J and makes a circuit through the evaporating-chamber D, and thence through the tube M and through the evaporating-chamber E to the outlet 0. The result is that such air making a longer circuit through impregnating-vapors and also passing through the chambers D E, which have a more readily-'vaporizable gasoline- I am aware that prior t-o-my invention it has been proposed to pass air or gas through a carbureting apparatus in contact with a hydrocarbon in such manner that some portion of the air or gas must pass through a longer circuit to the exit-pipe than the other portion or portions. I am not aware, however, that prior to my invention heating and illuminating fluids have been manufactured at one operation by passing air or gas through an impregnating-vapor, causing a part of the air to travel a short circuit through the vapor to produce a heating-fluid, and another part of the air to travel a long circuit through the vapor to produce the illuminating-fluid, and finally separately conducting the heating and the illuminating fluids through independent and disconnected conduits for the diiferent uses herein set forth, whereby one fluid can be conducted to a stove-for example, for heating the sameand the other fluid conducted to gas-burners for illuminatingan apartment.

When the apparatus is to be emptied or cleaned, access to the various chambers is readily obtained by means of the tubes G, L, N, and P.

The storage-chambers B O, as seen, are independent from one another, so that each chamber will of gasoline; Of course, in place of gasoline any other substance which yields suitable combustible impregnating-vapors maybe used in the apparatus.

What I claim as new, and desire to secure by Letters Patent, is-

The herein-described method of manufacturing heating and illuminating fluids at one operation, which consists in difierentially carbu retin g air or gas by passing said air through a suitable charging or impregnating vapor and causing part of said air to make a short circuit through said vapor for the production of a heating-fluid and another part of said air to make along circuit through said vapor for the production of an illuminating-fluid, and, finally, separately conducting the diiferentlycarbureted fluids through independent and disconnected conduits for the different uses, as herein set forth.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
